Swift[edit]
var line : String?
repeat {
line = readLine()
if let text = line {

C[edit]
#include <stdio.h>
#include <ctype.h>
#include <string.h>
int main( void ) {
char *line;
fgets(line, 255, stdin);
size_t line_length = strlen(line);
for (size_t i = 0; i < line_length; i++) {
if (isdigit(line[i])) {
printf("%c\n",line[i]);
}
}
return 0;
